Support helped but took quite some effort
The help I got over the phone eventually fixed the issues I was facing, so I can say it was successful. On the other hand, the amount of effort required from my side was significant. I first had to explain the software and database problem in detail multiple times before the support understood exactly what was wrong. The process to escalate the ticket was slow, and I had to follow up myself repeatedly to get updates. While the automatic update feature on the software did relieve some issues, several calls and back-and-forth were necessary before anything concrete happened. The billing and sign-up process did not cause any trouble during this time, thankfully. The dialer tool was fine after solving the initial problems but getting to that stage was a bit of a chore. Overall, the outcome was good, but achieving it was not effortless. If the system can speed up the initial problem recognition by support, that would help customers a lot in future. For now, I would say it's usable but with patience required.
